Summary
Built in 1960, this earth dam stands at a height of 13 feet and has a length of 580 feet, with a storage capacity of 58 acre-feet. Managed by the South Dakota Department of Environment and Natural Resources (DENR), the dam is regulated, permitted, inspected, and enforced by the state agency to ensure its safety and compliance with regulations.
Despite being classified as having a low hazard potential, the condition of Sd Noname 43 has not been rated, and key information such as the last inspection date and condition assessment are not available. Emergency action plans and risk assessments are also lacking for this dam. With a maximum discharge capacity of 500 cubic feet per second, proper management and maintenance are crucial to prevent any potential risks and ensure the safety of downstream communities and ecosystems.
The dam is not under the jurisdiction of the U.S. Army Corps of Engineers and does not have associated federal agencies for funding or operations. The Natural Resources Conservation Service is listed as the designer of Sd Noname 43, indicating a focus on environmental conservation and sustainable resource management. For water resource and climate enthusiasts, monitoring the condition and management of dams like Sd Noname 43 is essential in safeguarding our water infrastructure and adapting to the changing climate.

Condition Assessment
SatisfactoryNo existing or potential dam safety deficiencies are recognized. Acceptable performance is expected under all loading conditions (static, hydrologic, seismic) in accordance with the minimum applicable state or federal regulatory criteria or tolerable risk guidelines.
Fair
No existing dam safety deficiencies are recognized for normal operating conditions. Rare or extreme hydrologic and/or seismic events may result in a dam safety deficiency. Risk may be in the range to take further action. Note: Rare or extreme event is defined by the regulatory agency based on their minimum
Poor A dam safety deficiency is recognized for normal operating conditions which may realistically occur. Remedial action is necessary. POOR may also be used when uncertainties exist as to critical analysis parameters which identify a potential dam safety deficiency. Investigations and studies are necessary.
Unsatisfactory
A dam safety deficiency is recognized that requires immediate or emergency remedial action for problem resolution.
Not Rated
The dam has not been inspected, is not under state or federal jurisdiction, or has been inspected but, for whatever reason, has not been rated.
Not Available
Dams for which the condition assessment is restricted to approved government users.
Hazard Potential Classification
HighDams assigned the high hazard potential classification are those where failure or mis-operation will probably cause loss of human life.
Significant
Dams assigned the significant hazard potential classification are those dams where failure or mis-operation results in no probable loss of human life but can cause economic loss, environment damage, disruption of lifeline facilities, or impact other concerns. Significant hazard potential classification dams are often located in predominantly rural or agricultural areas but could be in areas with population and significant infrastructure.
Low
Dams assigned the low hazard potential classification are those where failure or mis-operation results in no probable loss of human life and low economic and/or environmental losses. Losses are principally limited to the owner's property.
Undetermined
Dams for which a downstream hazard potential has not been designated or is not provided.
Not Available
Dams for which the downstream hazard potential is restricted to approved government users.
